Soil fungal community comparison of different mulberry genotypes and the relationship with mulberry fruit sclerotiniosis

Abstract

Mulberry fruit sclerotiniosis is a common soil-borne disease. We hypothesize that there is a relationship between the incidence of mulberry fruit sclerotiniosis and the soil fungal community. Therefore four mulberry genotypes with different resistance to sclerotiniosis were selected to study their soil fungal community under the same condition. A total of 6 phyla and 93 genera were identified from all mulberry samples. Genera affected by genotype, cover, and genotype by cover interactions, were 23, 20, and 11, respectively. There were 10 genera that differed between the resistant cultivars and the susceptible cultivars. In addition, the relative abundances of Humicola and Mortierella in the resistant mulberry cultivars with the cover treatments were significantly higher than that of in the susceptible cultivars. However, the relative abundance of Sclerotiniaceae and Scleromitrula that may cause sclerotiniosis in the uncover treatments were significantly higher compared with the cover treatments. The results suggested that the genotype of mulberry has a significant impact on the soil microbial community that may result in differences in resistance to sclerotiniosis, and covering could reduce the relative abundance of Sclerotiniaceae or Scleromitrula.

Physiological and transcriptome analyses of photosynthesis and chlorophyll metabolism in variegated Citrus (Shiranuhi and Huangguogan) seedlings

“…Genes differentially expressed between two groups were analyzed using the DESeq R package (1.10.1), which provides statistical algorithms for detecting DEGs using a model based on a negative binomial distribution. The resulting P values were adjusted using the Benjamini and Hochberg’s approach to control the false discovery rate 52 . Genes with an adjusted P value < 0.05 following the DESeq analysis were considered to be differentially expressed between groups 52 .…”

A Microbiome Study Reveals Seasonal Variation in Endophytic Bacteria Among different Mulberry Cultivars

“…This disease is mainly caused by soil-borne fungal pathogens in the family Sclerotiniaceae such as Ciboria shiraiana [14], Ciboria carunculoides [15], Sclerotinia sclerotiorum [16], and Scleromitrula shiraiana [17]. Yu et al [18] reported that different mulberry cultivars had significantly different impacts on the soil microbial community, resulting in the differences in the level of resistance to sclerotiniosis. Little information is available, however, about the distribution of endophytic bacteria in different mulberry cultivars and their potential role in resistance to sclerotiniosis.…”

Influence of Peanut Cultivars and Environmental Conditions on the Diversity and Community Composition of Pod Rot Soil Fungi in China

“…Community correlation with peanut cultivars and environmental variables. Studies on the soil microbial communities of some crops have reported that microbial communities differed between different pathogen-resistant cultivars [ 27 ]. However, in this study, the three peanut cultivars were all susceptible to pod rot pathogens.…”

“…4 and 5 ). All of the above results suggest that cultivars did affect the soil fungal community diversity and abundance which may affect the resistance to fungal soil-borne pathogens [ 27 ]. In addition, the presence of Fusarium fungal pathogen “ Fusarium sp.…”
